CUTTER-HEAD.

SPECIFICATION forming part of Letters Patent No. 723,066, dated March17, 1903.

Application filed July 23,1902.

To a. whom it may concern:

Be it known that I, FRANK STU'rzMAN,a citizen of the United States,residing at Willowing is a specification.

My invention relates to cutter-heads, apd is designed to provide astable construction adapted to sustain the wear and strain to which suchheads are subjected, to furnish a secure grip for the cutter and oneholdingit forcibly against its seat, and, further, to provide securingmeans flush with the edge of the cutter or within the lines thereof, soas to allow the cutter-head to be used insituations requiring a flushsurface with the face of the cutter. e

In the drawings, Figure 1 is a sectional View, taken centrally, ofaforln of head provided with my improvement. Fig. 2 is an elevation ofthe head. Fig. 3 is a plan view.

The body of the head is shown at A, of or dinary or improvedconstruction, having the usual central opening a. The cutter-blades areshown at B. The head has a seat b, located above a flange c, and to thisseat the cutter-blades are held by a clamping head and bolt. At thejunction of the seat I) and flange c a groove (1 is made, ha'vingastraight wall, forming a continuation oftheseat I),

while the opposite wall of the groove formed i in the flange isinclined. The cutter-blade has a rear face e, conforming to and fittingthe seat I), and is also provided with tapering upper and lower edges,the lower edge fitting the groove (1 and corresponding thereto. Theupper edge is beveled and projects beyond the body A. This edge fits agroove h, similar to the groove 01, but formed in the headed end f of abolt 9. .The bolt gpasses through the bodyl'A and terminates in the headf, which is flat and elongated, to engage the cutter sufficiently tohold it securely. The bolt is held in place by a nut g, fitting againstthe opposite face. of the body fromthat upon which the head f islocated. The groove 71 has also one straight wall and one inclined$erial No. 116,725. (No model.)

wall and is adapted to fit the corresponding edge of the cut-ter. Thebolt 9 has a screw cap or nut on its opposite end, and pressure appliedthereto draws the cutter closely to its seat by reason of its inclinededges fitting the like grooves. It will also be seen that the cuttersproject beyond the headed ends f, so that a flush surface is provided,and the headed ends are thus in the same plane or within the lines ofthe cutters, and the head is thus adapted for situations where otherwiseit could not be used.

What I claim is- 1. A cutter-head comprising a bodyA, having a flange cprojecting from its periphery and a seat I) on its periphery adjacentsaid flange and having also a groove (1 at the junction of the said seatb and the side face of said flange, which groove has one wall forming acontinuation of the seat I) and the other wall inclined, a cutter havinga portion resting on the seat I) and extending beyond the said seat witha beveled edge on the projecting portion and having also a beveled loweredge resting in the groove, and a bolt having a head formed with agroove to receive the projecting beveled edge of the cutter, said boltextending through the body and having a not on the opposite side of thebody from the head, substantially as described.

2. In combination, a head having a flange c with a groove at thejunction of said flange and the peripheral face of the head, said groovehaving a beveled outer wall, a cutter having a portion seated againstthe peripheral face of 'the'head with a beveled edge in said groove anda beveled edge projecting beyond the head and means engaging saidprojecting beveled edge to draw the cutter firmly against its seat,substantially as described.

In testimony whereof I affiX my signature in presence of two witnesses.

FRANK STUTZMAN. Witnesses:
